Last night, I managed to get some of my very non-gamer friends to play Katamari Damacy.  They said they wanted to play something ridiculous, and I couldn't think of a more ridiculous game.  Nevertheless, these guys are not as open-minded as I am, nor do they have any vested interest in videogames or Japan, so I was worried that they just wouldn't get it.

But they definitely got it.  They were like, 'wtf?' at first, but they ended up playing for quite a while.  I even left the room and they were still rolling sh*t up.  Needless to say, it was very gratifying as I watched people who aren't even casual gamers get really into rolling over sumo wrestlers with a giant ball of crap.
